\VILLIAM F. SEFTON, OF CANTON, OHIO.

POINT.

SPECIFICATION forming part of Letters Patent No. 385,529, dated July 3,1888.

Application filed April 25, 1858.

To aZZ whom it may concern:

Be it known that 1, WILLIAM F. SEFTON, a citizen of the United States, residing at Ganton, in the county of Stark and State of Ohio, have invented certain new and useful Imp rovements in Plow-Points; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon, in which Figure 1 is a top View of a plowsharc, showing the detachable point removed. Fig. 2 is a sectional view showing the detachable point placed in proper position. Fig. 3 is a top view of the detachable point. Fig. 4 is a side View of the detachable point and a portion of the share; Fig. 5, an under side view of a port-ion of the share at the place of attaching the detachable point.

The present invention has relation to plowparticularly pointed out in the claim.

Similar letters of reference indicate corresponding parts in all the figures of the drawlugs.

In the accompanying drawings, A represents the share, which may be substantially of the form shown, and is provided with the grooves or recesses a and b, which are located substantially as illustrated in Figs. 1 and 5, and are for the purpose of receiving the projections a and b. The detachable point B is substantially of the form shown in the drawings, and is provided with the \l-shaped recess 0, which is located substantially as illustrated in Figs. 1 and 4, and is for the purpose of receiving a corresponding-shaped portion upon the side of the share A, as illustrated in Fig. 4.

Serial No. 271,803.

(No model.\

The detachable point B is securely. attached to the share A by means of the clamping-bolt d, the head of which is sunk into the share A. It will be seen that by my peculiar manner of attaching the point B to the share A the workingsurfiices of said parts will be a continuation of the same curvature, thereby offering no extra resistance in the proper working of the plow. Itwill also be seen that by providing the projections a and I) the point B will' be securely held in proper position laterally, and at the same time strengthen the detachable point.

It will also be seen that when the point B has become worn from use a new one can be attached at a very small expense.

I am aware that detachable points have heretofore been attached to plowshares, and hence do not claim that feature, broadly; but

WVhat I do claim, and desire to secure by Letters Patent, is-

The combination of a plowsharc provided WILLIAM E. SEFTON.
